Fred McNeill and the Chronic Traumatic Encephalopathy research case / 2000s-2010s
Fred McNeill spent 12 seasons as a hard-hitting linebacker for the Minnesota Vikings, appearing in Super Bowls IX and XI before retiring in 1985 and later graduating at the top of his class from William Mitchell College of Law. In his later years, however, the cumulative cost of his football career emerged in the form of dementia and severe neurological decline. In 2009, McNeill became the first former NFL player reported to have chronic traumatic encephalopathy, or CTE, diagnosed while he was still alive. Researchers observed evidence consistent with the disease in brain scans, an especially significant development because CTE had historically been confirmed only after death through examination of brain tissue.
McNeill was diagnosed with amyotrophic lateral sclerosis in March 2014 and died from ALS on November 3, 2015, at age 63. After his death, Dr. Bennet Omalu conducted an autopsy that confirmed the CTE diagnosis, validating the earlier findings from the living-patient study. McNeill's case became an important piece of the growing evidence that repeated head impacts in football can produce long-term neurological injury and helped drive efforts to identify CTE before death. He is among hundreds of former NFL players whose brains have subsequently been diagnosed with CTE, making his story a grim bridge between football's celebrated era of violent defense and the modern reckoning over concussion-related disease.
